Method/Apparatus/Procedure:
   The synthetic method was used. The reagents, about 1 mL of (1) and 1 to 1.5 mL of (2), were introduced and stirred with a thermometer while the tubes were warmed gradually in a bath of water. The temperature of disappearance or reappearance of the cloud due to two liquid phases was read three or four times in each direction. If the final position of the interface was not near the middle of the liquid, the volumes of the reagents were adjusted to make it so.

Source and Purity of Materials:
   (1) Source not specified, pure grade reagent.
   (2) Some aromatic hydrocarbons (*) were available from the Socony-Vacuum Oil Co.; others were made by alkylation of benzene, toluene, ethylbenzene, naphthalene or tetralin with ethene, propene, 2-butene, isobutene or pentene, using aluminum chloride as ca
